Agent skills for the JavaScript and TypeScript codebase intelligence layer.
Agent skills for fallow, Rust-native codebase intelligence for JavaScript and TypeScript. The free static layer finds unused code, circular dependencies, code duplication, complexity hotspots, and architecture boundary violations in milliseconds. The optional paid runtime layer (Fallow Runtime) adds production execution evidence so agents can delete cold code, flag hot-path changes, and retire stale flags with proof. 90 framework plugins, zero configuration. Works with any agent that supports the Agent Skills specification: Claude Code, Cursor, OpenAI Codex, Windsurf, GitHub Copilot, Gemini CLI, Amp, and 30+ more.
Linters enforce style. Formatters enforce consistency. Fallow enforces relevance. Linters work file by file. TypeScript works type by type. Neither builds the full module graph, so neither can see what nothing depends on. Fallow does, in milliseconds. These skills teach agents how to use fallow effectively: which commands to run, what flags to use, how to interpret output, and how to avoid common pitfalls.
Clone or copy the skill directory into your agent's skills location. This skill follows the open Agent Skills specification and works with any compatible agent.
Prerequisites
Fallow must be installed in the target project:
npm install -g fallow # prebuilt binaries
npx fallow dead-code # or run without installing
See the installation guide for all options including cargo install fallow-cli.
AI-powered codebase understanding assistant. Learn design patterns, analyze impact, trace code flows, and understand any codebase through information theory principles. Includes 6 Agent Skills for automatic analysis triggering.
